 4. Appearance Sizes And Assembly Style of ZLYJ reduction gearbox


1) Verify transmitted power. For ZLYJ reduction gearbox, the behavior coefficient has been considered in the input powers and the output torques in the Table, therefore it can be selected directly from Table. The output torque in the table is also the main basis to make selection. If the normal driving ratio in the table couldn’t meet the requirement, please contact with our company.

2) Verify thermal power. For ZLYJ reduction gearbox , make selection as per the notes on the Table.

3) Verify assembly and connection sizes. If the sizes you need is different from those in the table, please contact our company.

4) Verify radial force of shaft extension. If the input shaft adopts connection style with pulley which can cause added radial force, it should confirm that the radial force at the middle of the input shaft extension if it is less than 125, here T1 means the input torque. If it is not enough, please contact with our company.




 5. Assembling, Application and Maintenance of ZLYJ reduction gearbox


1) When lifting the ZLYJ reduction gearbox, the ring screw should be used.

2) Take care to prevent moisture when the ZLYJ reduction gearbox is in transportation or storage. If do not assemble in half a year after it is arrived, the exposure surface should be coated with antirust oil.

3) The base to assemble the ZLYJ reduction gearbox should be plain with enough strength and rigidity. Under circumstance the anchor bolts are evenly tightened it should ensure that the screw rod inserted into the output shaft should be rotated freely without blockage. The assembling error of the coupler should do not excess its allowed tolerance so as to avoid from added force and to cut down the life of the bearings.

4) The ZLYJ reduction gearbox should pass through strict test running inspection before they are delivered. Only all index are in according to the requirement, can they be put into use directly after delivery. Before application, it should be filled with mid-extreme pressure gear oil N220 up to the upper limit of the oil mark (N150 if circulation pump lubrication is used.) if the reducer has pipe style oil cooler, the run the reducer under no-load for a short period of time after oil is filled, then fill oil again up to the upper limit of the oil mark.

5) For the ZLYJ reduction gearbox with motor oil pump, before adding load, it should switch on the oil pump of the motor to run the reduction gearbox under no-load for a short period of time so as to facilitate full lubricant points.

6) Replace oil when the ZLYJ reduction gearbox is initially running for 300 hours, and change oil once for every 3000-4000 running hours thereafter. The maximum interval between oil replacements should be no longer than 18 months. When replacing, first clean box body, oil filter and oil discharge screw plug.
